The invention discloses a variable pesticide application control method for a forestry aviation helicopter. The method comprises the following steps of S1, setting a flight height, a flight speed and a pesticide application amount of hectare as independent variables, and setting a valve opening degree as a dependent variable; S2, determining the relationship between the dependent variable and the hectare pesticide application amount; S3, determining the relationship between the navigational speed and the pesticide application amount of hectare; S4, determining the relationship between the flight height and the pesticide application amount of hectare; S5, establishing an aviation variable pesticide application mathematical model through the steps S2, S3 and S4; S6, collecting data of the flight height, the flight speed and the flow of the pesticide liquid of the helicopter in real time, and calculating through the aviation variable pesticide application mathematical model to obtain the opening degree of the valve; when data of the sailing height, the sailing speed and the flow are changed, the opening degree of the valve is adjusted in time so as to ensure that the pesticide applying amount of hectare is not changed.
本发明公开了一种林业航空直升机变量施药控制方法,包括以下步骤:S1、将航高、航速、公顷施药量设定为自变量,将阀门开度设定为因变量;S2、确定因变量与公顷施药量的关系;S3、确定航速与公顷施药量的关系;S4、确定航高与公顷施药量之间的关系;S5、通过步骤S2、S3、S4建立航空变量施药数学模型;S6、实时采集直升机的航高、航速以及药液的流量数据,并通过航空变量施药数学模型计算得到阀门开度;当航高、航速、流量数据发生变化时,及时对阀门开度进行调节,以保证公顷施药量不变。
